virtual	~CaptureTracker ()
virtual void	tooManyUses ()=0
virtual bool	shouldExplore (Use *U)
virtual bool	captured (Use *U)=0

Detailed Description

This callback is used in conjunction with PointerMayBeCaptured. In addition to the interface here, you'll need to provide your own getters to see whether anything was captured.

Member Function Documentation

virtual bool llvm::CaptureTracker::captured ( Use *  U )

pure virtual

captured - Information about the pointer was captured by the user of use U. Return true to stop the traversal or false to continue looking for more capturing instructions.

Referenced by llvm::PointerMayBeCaptured().

bool CaptureTracker::shouldExplore ( Use *  U )

virtual

shouldExplore - This is the use of a value derived from the pointer. To prune the search (ie., assume that none of its users could possibly capture) return false. To search it, return true.

U->getUser() is always an Instruction.
